RAT GUARD.

Specification of Letters Patent.

- Patented June 20,

Application filed October 17, 1921. Serial No. 508,319."

To all whom it may concern;

Be it known that I, Ann COHEN, a citizen of Russia, and residing at Brooklyn, in the county of Kings and State of New York, have made a certain new and useful Invention in Rat Guards, of which the following is a specification.

This invention relates to rat guard devices, and has for its object the provision of a simple and efiicient means which may readily be applied to anchor chains and ship hawsers for protecting ships lying anchored at docks from being boarded by rats.

A further object of my invention is the provision of an armored guard which may be cheaply made and readily applied to fit closely around ropes, chains, posts and the like. for the protection against rodents.

My device is further of such nature as to offer protection against abrasion and cutting of hawsers which are used in anchoring or tying ships at docks.

Other objects of the invention will be come apparent hereinafter from the specification and claims, and I attain these objects by the device illustrated in the accompanyin drawing, of which,

*ig. 1 is a view of an elevation of my device applied to a rope;

Fig. 2 is a bottom view of the same;

Fig. 3 is a section taken on the line 33 of Fig. 2, looking in the direction of the arrows;

Fig. 4 is a section taken on the line 4.4; and

Fig. 5 is a section of a modified form of my device.

Similar numerals refer to like parts throughout the several views.

Referring now to the drawing, the essential parts of my invention comprise two side members 6 and 7, of any desired length, and formed so as to fit any desired rope or like device to be protected. For convenience, the two parts 6 and 7 may be curved sufficiently and secured at 8 by rivets or otherwise, so as to be resiliently or flexibly held.

In the specific construction I have shown one of the members 6 as terminating in serrations 9 for the purpose hereinafter specified. The lower portions of the two curved members may be conveniently beaded as shown at 10 and 11, and the beads may be strengthened by a rib 12. Any suitable locking means may be provided such as, for

instance, clamp 13, which is permanently attached to one of the ribs 12, and may be locked or unlocked by simply surrounding the other rib. It is obvious that other locking means may be provided if desired.

Instead of, forming the side members of two parts, it is obvious that a single sheet of metal can be bent upon itself and shaped as illustrated in Fig. 5, so as to form the two side members. 11 this case the side members 6 and 7 terminate in a ridge which is formed into saw-tooth or serrations 9 similar to that illustrated in Fig. 1.

In applying my device to ropes and hawsers, the same is clamped in position as shown in Fig. 1, and it is my purpose to have the serrations on the upper side of ropes if the same are inclined so as to prevent the rodent from climbing on the ridge thereof, or from holding on the sides. The guard is usually and conveniently con structed of sheet metal of suitable thickness and strength, and it is obvious that the length of the guard may be such as to sufficiently protect the ropes also against abrasion when the ships are lying at anchor. By means of my special construction I am enabled to quickly guard ropes against rats boarding a vessel while it is anchored.

It is obvious that minor details and various modifications may be constructed fall'- ing wholly within the spirit and scope of my invention, as the same is set forth in the ap ended claims. I

ut having now set forth the objects and nature of my invention and the manner of carrying the same into practical operation, what I claim as new and useful and of my own invention and desire to secure by Letters Patent is:

1. A rat guard comprising side members terminating in serrations along a median line.

2. A rat guard comprising curved side members terminating in cutting means along a median line, and means for locking said members in position.

3. A rat guard comprising curved side members terminating in a cutting edge, said members being flexibly united at said edge for permitting the side members to be applied to an anchor rope.

4. A rat guard comprising elongated curved members having outer smooth sides,

said members having heads at adjacent edges, and terminating in a ridge common to both members at the opposite edge or side.

5. In a rat guard, curved elongated shields Inovably united and formed into a ridge, :1 cutting edge on said ridge, and means for holding said shields in fixed relation to the member on which the guard is applied.

6. In a rat guard, curved elongated shields 1O movably united and formed into a ridge, a

cutting edge on said ridge, and inez'ms for holding said shields in fixed relation. to the member on which the guard is applied, said cutting edge comprising saw tooth. projections arranged at angles to the base line of said ridge.

In testimony whereof I have hereunto set my hand on this 26th day of August, A. D.
